The coordinates on a map for city a are (55, 11) and those for city b are (116, 65). note that coordinates represent miles. find the distance between the cities to the nearest mile.

The distance between the cities is 81 miles

Step-by-step explanation:

* Lets explain how to find a distance between two points

- The distance between the two pints and

  is

* Lets solve the problem

∵ City A located at point (55 , 11)

∵ City B located at point (116 , 65)

- Let point = (55 , 11) and point

  = (116 , 65)

∴ and

∴ and

- By using the rule above

∴

∴ The distance between the cities is 81 miles

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
